I am having a flask server in a docker container and wanna actually import some of my own python files also on this server. Everytime I am trying this I am getting a "ImportError: cannot import name ‘ACCESS_DEFAULT’.
I found already question about a similiar issue here (Importing python file in docker container) on stackoverflow but I am struggeling to get it working.
The error statement looks like this:
Attaching to g2_app_1
app_1 | Traceback (most recent call last):
app_1 | File "app.py", line 4, in <module>
app_1 | from inferenceMachine import calculateRouteAndNavigateMBot
app_1 | File "/environmentservice/inferenceMachine.py", line 3, in <module>
app_1 | from mBotControlPy.pathToNavigationConverting import convertPathToNavigationCommands
app_1 | File "/environmentservice/mBotControlPy/pathToNavigationConverting.py", line 3, in <module>
app_1 | from mmap import ACCESS_DEFAULT
app_1 | ImportError: cannot import name 'ACCESS_DEFAULT'
g2_app_1 exited with code 1
My fow my project structure looks like:
|-Dockerfile
|-app.py
|-requirements.txt
|-inferenceMachine.py
|_
mBotControlPy
|-mBotControl.py
|-pathToNavigationConverting.py
|_
intelligentPathFindingPy
|-pathFindingAlgorithm.py
And my Dockerfile configuration is here:
# start from base
#FROM ubuntu:18.04
FROM python:3.6.8-alpine
LABEL maintainer="Group2"
#RUN apt-get update -y &&
# apt-get install -y python-pip python-dev
COPY ./requirements.txt /environmentservice/requirements.txt
#ADD intelligentPathFindingPy /environmentservice/intelligentPathFindingPy
#ADD mBotControlPy /environmentservice/mBotControlPy
#COPY ./inferenceMachine.py /environmentservice/inferenceMachine.py
#COPY ./app.py /environmentservice/app.py
WORKDIR /environmentservice
RUN pip install -r requirements.txt
COPY . /environmentservice
CMD [ "python", "./environmentservice/app.py" ]
Do you have some hints what I am doing wrong in this case? I assume it is having something to do with the structure of the files in the Dockerfile.

You are using
python-3.6.8
butACCESS_DEFAULT
has been added tommap
in Python 3.7. Try to update Python version in the Dockerfile (FROM line)You are using a Python 3.6 image but the
ACCESS_DEFAULT
constant was added to themmap
module in Python 3.7.From the docs:
Either change the image to a Python 3.7 image:
or don’t use
mmap.ACCESS_DEFAULT
.
